I recently ran in to a problem with the Smarty debugging console falling over when faced with a template that has objects assigned as variables. I've updated the modifier.debug_print_var.php to allow for objects as well as arrays, and the replacement file is attached to this email.

It looks like something stripped the attachment along the way, so I've pasted the file in to /this/ email :) ============ <?php /* * Smarty plugin * -------------------------------------------------------------
